Secondly, "Using reciprocity successful". After a friend has presented this topic. I agree with this topic. To create a successful relationship can be achieved by giving gifts to the little to impress. For example in the clip. The employees give Mint candy for customers to come dine in the restaurant of him. Which in the clip has said "giving a little gift to customers will help establish a good relationship between customers and the restaurants. It will make impresses customers and come back to dine again". But if want to be good more than that. Said admired is the best gift. Can be seen from in the clip. When employees said admired. It will make the customers have impression in the restaurant increase more 20%.
